sensitive-browser

Original：🇺🇸 English

Translated

Execute sensitive browser actions (login, payments, form filling) outside the core agent loop using a dedicated CLI tool. Use when Claude needs to handle credentials, payment information, or other sensitive data in browser automation workflows. Triggers when users ask to log into websites, fill payment forms, or perform authenticated browser actions where sensitive data must be kept secure and separate from the main agent context.

Sensitive Browser

Execute sensitive browser actions securely by delegating credential handling, payments, and form filling to a dedicated subprocess with isolated context.

When to Use

User asks to log into a website with credentials
User needs to fill payment information on a checkout page
User needs to complete forms with personal/sensitive data
Browser automation requires authentication handoff

Prerequisites

The

ATXP_CONNECTION

environment variable must be defined for LLM access. This provides the connection string to the ATXP platform.

If not configured, see the ATXP CLI for setup instructions.

Workflow

1. Prepare Sensitive Data File

Create a JSON file with the user's sensitive data. Ask the user for the values needed:

json

{
  "credentials": {
    "username": "user@example.com",
    "password": "secret"
  },
  "payment": {
    "cardNumber": "4111111111111111",
    "expiry": "12/28",
    "cvv": "123",
    "billingZip": "94102"
  },
  "personal": {
    "fullName": "Jane Doe",
    "phone": "+1-555-0123",
    "address": "123 Main St"
  }
}

Only include the fields needed for the task. Store securely and delete after use.

2. Execute the Sensitive Action

bash

npx sensitive-browser "<task>" \
  --sensitive-data ./creds.json \
  --url <target-url> \
  --state ./session.json \
  --output ./session.json

Options:

Option	Description
`<task>`	Natural language task (e.g., "log in with credentials")
`-d, --sensitive-data <path>`	Path to sensitive data JSON (required)
`-u, --url <url>`	Target URL to navigate to
`-s, --state <path>`	Playwright storage state to load
`-o, --output <path>`	Output path for updated state

3. Integration with agent-browser

When used with agent-browser, hand off session state:
